Conversion Module Installation and Application Considerations
This Bul. 1492 cable consists of a cable wired to one 1756-IA16 RTB. Recommended cable lengths of 0.5M or 1.0M
(005=0.5M, 010=1.0M). See table 2 for other lengths.
The input delay times for the 1771-IAD module versus the 1756-IA16 module are as follows:
1771-IAD 1756-IA16 w/ 1492-CONCAB005X
a) Off-to-On Delay 5ms (+/-3ms) @120VAC 10ms max (plus selectable filter)
b) On-to-Off Delay 25ms (+/-5ms) 8ms max (plus selectable filter)
The 1771-IAD module is rated 79V to 138V AC or DC. The 1756-IA16 module is rated 74V to 132V AC. If the input
source voltage is DC use a 1756-IH16l and 1492-CM1771-LD002 conversion module.
Refer to your 1771-IAD and 1756-IA16 Installation Manual wiring schematics and diagrams for more details.
